Never been used. Sells for 33.50. I will send this one off to you for 20.00, including shipping. It is shown here: http://ameda.com/products/manual.htm number 17061. It is a great little hand pump. ALthough this one has never been used I had another just like it. The pumping truly is one-handed, and it is a comfortable motion unlike the Medela where you have to use two hands.
